What is the standard form of a linear equation?

• Ax + By = C

• By = Ax + D

• C = Ax - By

• Ax + C = By

y=-11x-2(18-6x)/5 шулууны налалтыг ол

(a)  

Answer explanation

y=-11x-2(18-6x)/5

y=-11x+2.4x-7.2

y=-8.6x-7.2

y=(-43x/5)-36/5

m=-43/5

Зурган дээрх f(x) шулуун нь g(x) шулуунтай(зурагт өгөгдөөгүй) перпендикуляр. f(x) ба g(x) шулуунууд (1, 5/2) цэг дээр огтлолцдог бол g(-1) утгыг ол.

(a)  

Answer explanation

f(x)=(1x/2)+2

m=1/2➡️-2

5/2=-2(1)+9/2

g(x)=-2x+9/2

g(-1)=2+9/2=6.5=13/2

Solve the system of equations: 2x + 3y = 6 and x - y = 1.

• (1, 1)

• (9/5, 4/5)

• (2, 0)

• (0, 2)

P шулуун координатын систем дээр өгөгдсөн ба (5, r ) цэг түүн дээр оршиж байгаа бол r хэд вэ?

• -5/3

• -11/6

• -11/7

• -12/7

Answer explanation

х цэгийн огтлол (7, 0)

y цэгийн огтлол (0, -6)

m=∆y/∆x

m=-6/7

y=(6x/7)-6

r=(30/7)-6

r=-12/7

Find the y-intercept of the equation 4x - 2y = 8.

• 0

• -2

• 2

• -4

Determine if the lines represented by y = 2x + 1 and y = 2x - 3 are parallel, perpendicular, or neither.

• coincident

• intersecting

• parallel

• perpendicular

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

• 1

• 2

• 3

• 4

Convert the equation 3x + 4y = 12 into slope-intercept form.

• y = 3/4x + 1

• y = -4/3x + 2

• y = 12 - 3x

• y = -3/4x + 3

If two lines have slopes of 1/2 and -2, are they parallel, perpendicular, or neither?

• coincident

• perpendicular

• parallel

• neither
